Abstract

Methods and apparatus to suspend packet switched services in a mobile network are disclosed. An example method includes sending from a mobile equipment a session management status message comprising a first indication indicating suspend packet data protocol context.

Claims

exact text as granted — not AI-modified
1 . A method in a user equipment, the method comprising:
 sending a first session management status message comprising a first indication indicating suspend packet data protocol context.   
     
     
         2 . The method of  claim 1 , wherein the first indication indicates that all packet data protocol contexts are to be suspended. 
     
     
         3 . The method of  claim 1 , wherein the first session management message includes a transaction identifier associated with a first packet data protocol context to be suspended. 
     
     
         4 . The method of  claim 3 , wherein the first session management message includes a suspension indicator indicating that all active packet data protocol contexts sharing a packet data protocol address and an access point name with the first packet data protocol context shall be suspended. 
     
     
         5 . The method of  claim 3 , wherein the first session management message includes a suspension indicator indicating that only the first packet data protocol context shall be suspended. 
     
     
         6 . The method of  claim 1 , wherein the first indication is a session management cause value. 
     
     
         7 . The method of  claim 6 , wherein the session management cause value is #113 Suspend PDP context. 
     
     
         8 . The method of  claim 1 , further comprising sending a second session management status message comprising a second indication indicating resume packet data protocol context. 
     
     
         9 . The method of  claim 8 , wherein the second indication indicates that all packet data protocol contexts are to be resumed. 
     
     
         10 . The method of  claim 8 , wherein the second session management status message includes a transaction identifier identifying a packet data protocol context to be resumed. 
     
     
         11 . The method of  claim 8 , wherein the second indication is a session management cause value. 
     
     
         12 . The method of  claim 11 , wherein the session management cause value is #114 Resume PDP context. 
     
     
         13 . The method of  claim 1 , wherein the first session management status message is sent when a circuit switch call is initiated. 
     
     
         14 . The method of  claim 1 , wherein the first session management status message is sent when the user equipment determines that packet switched communications may interfere with circuit switched communications. 
     
     
         15 . The method of  claim 1 , wherein the first session management message includes a first transaction identifier associated with a first packet data protocol context to be suspended and a second transaction identifier associated with a second packet data protocol context to be suspended. 
     
     
         16 . A method in a network equipment, the method comprising:
 receiving a first session management status message comprising a first indication indicating suspend packet data protocol context.   
     
     
         17 . The method of  claim 16 , wherein the first indication indicates that all packet data protocol contexts are to be suspended. 
     
     
         18 . The method of  claim 16 , wherein the first session management message includes a transaction identifier associated with a first packet data protocol context to be suspended. 
     
     
         19 . The method of  claim 18 , wherein the first session management message includes a suspension indicator indicating that all active packet data protocol contexts sharing a packet data protocol address and an access point name with the first packet data protocol context shall be suspended. 
     
     
         20 . The method of  claim 16 , further comprising receiving a second session management status message comprising a second indication indicating resume packet data protocol context. 
     
     
         21 . A user equipment comprising:
 a component configured to send a first session management status message comprising a first indication indicating suspend packet data protocol context.   
     
     
         22 . The user equipment of  claim 21 , wherein the first indication indicates that all packet data protocol contexts are to be suspended. 
     
     
         23 . The user equipment of  claim 21 , wherein the first session management message includes a transaction identifier associated with a first packet data protocol context to be suspended. 
     
     
         24 . The user equipment of  claim 23 , wherein the first session management message includes a suspension indicator indicating that all active packet data protocol contexts sharing a packet data protocol address and an access point name with the first packet data protocol context shall be suspended. 
     
     
         25 . The user equipment of  claim 21 , wherein the component is configured to send a second session management status message comprising a second indication indicating resume packet data protocol context. 
     
     
         26 . The user equipment of  claim 21 , wherein the first session management status message is sent when the user equipment determines that packet switched communications may interfere with circuit switched communications. 
     
     
         27 . The user equipment of  claim 21 , wherein the first session management message includes a first transaction identifier associated with a first packet data protocol context to be suspended and a second transaction identifier associated with a second packet data protocol context to be suspended. 
     
     
         28 . A network equipment comprising:
 a node configured to receive a first session management status message comprising a first indication indicating suspend packet data protocol context.   
     
     
         29 . The network equipment of  claim 28 , wherein the first indication indicates that all packet data protocol contexts are to be suspended.
